In the world of Jujutsu Kaisen, familial ties are rarely straightforward. Bloodlines intertwine with curses, and lineage is often manipulated by forces beyond human comprehension. Among the many mysteries that unfold throughout the series, one of the most intriguing is the relationship between Yuji Itadori and Choso. At first glance, they seem to be on opposing sides, but as the story progresses, their bond takes a surprising turn, leading fans to question the nature of their connection.
What makes their relationship even more compelling is the revelation that they share a common parent, though not in the traditional sense. Unlike typical brothers, their connection is steeped in cursed energy and the experiments of a sinister mastermind. Choso, a cursed spirit with deeply ingrained emotions, finds himself inexplicably drawn to Yuji, setting off a series of events that change both of their fates forever.
As we delve deeper into this fascinating dynamic, we’ll explore how Yuji and Choso’s shared lineage influences their actions, their struggles, and the overarching conflict in Jujutsu Kaisen. Whether you’re a longtime fan or a newcomer looking to understand the depth of their bond, this breakdown will shed light on the truth behind their connection and what it means for the story as a whole.
Who Are Yuji Itadori and Choso?

Before we go into the intricacies of their shared bloodline, it’s essential to understand who these two characters are.
Yuji Itadori: The Protagonist with a Powerful Curse
Yuji Itadori is the main protagonist of Jujutsu Kaisen. He begins his journey as a regular high school student with an extraordinary physical ability, which quickly comes into play when he consumes a cursed object—a rotting finger of Ryomen Sukuna, the King of Curses. This act triggers a series of events that lead him into the world of jujutsu sorcery, where he becomes a vessel for Sukuna, carrying the curse inside him.
Yuji’s natural kindness and determination set him apart from other characters. He’s determined to help others, even at the cost of his own life. His bond with his friends and allies, including Satoru Gojo, Megumi Fushiguro, and Nobara Kugisaki, only deepens his character’s emotional complexity. However, his connection to Sukuna and his struggle with his identity as a vessel make his character arc compelling.
Choso: The Cursed Womb of a Human
Choso, on the other hand, is one of the cursed spirits who appears to have more human-like qualities. He is part of a group of cursed beings known as the Cursed Wombs, created by the mysterious villain Noritoshi Kamo. Choso and his brothers—specifically, the brothers in the Cursed Womb—are central to some of the story’s darker elements, which involve the creation and manipulation of curses.
Choso’s journey is complicated by his emotions and a desire for revenge, particularly after the death of his brothers. His path intertwines with Yuji’s when he comes to believe that Yuji is somehow related to his family, though the truth is more complex and layered than Choso initially realizes.
Are They Really Brothers?

The simple answer is: Yes, Yuji Itadori and Choso share a unique family connection. However, their relationship isn’t what one might expect based on traditional family dynamics.
The Truth About Their Parentage
Yuji and Choso’s relationship goes beyond the simple notion of being half-brothers or adopted siblings. Their common parent is not a typical biological parent but a key figure in the story’s larger curse-based narrative. The revelation is tied to their shared heritage as descendants of a powerful cursed lineage.
Yuji Itadori’s mother’s backstory, though tragic and not entirely fleshed out in the early parts of the series, plays a significant role in explaining this connection. It is revealed that Yuji’s mother had a deeper link to the world of curses than initially apparent. While much of this remains shrouded in mystery, hints from the story and Choso’s actions indicate that Yuji’s mother and Choso’s creation are intricately connected.
The fact that Yuji and Choso are bound by a common parent highlights the intricate web of relationships in Jujutsu Kaisen, with each character’s backstory playing a crucial role in how the narrative unfolds.
Choso’s Role in the Reveal
Choso’s emotional response when he realizes the connection between himself and Yuji speaks volumes. Initially, Choso is blinded by rage and sorrow over the deaths of his brothers. However, upon realizing that Yuji is tied to his bloodline, he faces a confusing internal struggle. Choso starts to see Yuji not as an enemy but as a figure who may share his pain and his family history.
This complicated relationship adds depth to Choso’s character, as it challenges his previous beliefs and motivations. His desire to protect his “brother” becomes more than just a matter of vengeance or familial duty—it becomes a crucial part of his identity.
The Impact of Their Relationship on the Story

The unexpected bond between Yuji and Choso has major implications for the broader narrative of Jujutsu Kaisen. Their familial connection adds another layer to the already complex relationships between cursed beings, jujutsu sorcerers, and cursed objects.
A New Dynamic in the Fight Against Curses
Yuji’s already strained relationship with Sukuna becomes even more complicated with the revelation that he shares a bloodline with Choso. It introduces new dynamics in the fight against curses, as both characters now share a common history and a deeper connection to the cursed world.
Moreover, Choso’s belief in his family bond with Yuji gives him a more human side. This complicates his role in the story as a cursed spirit and forces both him and Yuji to question the nature of their existence.
An Emotional Tension
The emotional tension between Yuji and Choso is palpable. On one hand, Yuji’s struggle with Sukuna and his own morality contrasts with Choso’s thirst for vengeance. On the other hand, the bond they share gives rise to the potential for growth, understanding, and ultimately, a deeper alliance between them. This complexity makes their relationship a central part of the evolving plot.
Yuji Itadori and Choso are indeed connected through a shared bloodline, with their familial relationship unfolding as a key plot point in Jujutsu Kaisen. Their connection adds emotional depth to both characters, bringing a new layer of complexity to the series’ already intricate storyline. As we see Yuji and Choso’s paths cross and their relationship develop, it’s clear that their common parent plays an essential role in shaping their identities and motivations.
Interestingly, despite their unconventional bond, Choso’s protective instincts toward Yuji parallel the way he once cared for his fallen brothers, making their connection one of the most heartfelt and unexpected relationships in the series.
